tomcat的classpath设置

在tomcat启动的时候，tomcat不会用JDK的classpath，这个是在tomcat启动的catalina.sh里面设置的

在catalina.sh的一百八十行左右的代码：

# Add on extra jar files to CLASSPATH
if [ ! -z "$CLASSPATH" ] ; then
  CLASSPATH="$CLASSPATH":
fi
CLASSPATH="$CLASSPATH""$CATALINA_HOME"/bin/bootstrap.jar


if [ -z "$CATALINA_OUT" ] ; then
  CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
fi


if [ -z "$CATALINA_TMPDIR" ] ; then
  # Define the java.io.tmpdir to use for Catalina
  CATALINA_TMPDIR="$CATALINA_BASE"/temp
fi


# Add tomcat-juli.jar to classpath
# tomcat-juli.jar can be over-ridden per instance
if [ -r "$CATALINA_BASE/bin/tomcat-juli.jar" ] ; then
  CLASSPATH=$CLASSPATH:$CATALINA_BASE/bin/tomcat-juli.jar
else
  CLASSPATH=$CLASSPATH:$CATALINA_HOME/bin/tomcat-juli.jar
fi

如果需要把自己的目录加进去的话，在下面加一句

# Add tomcat-juli.jar to classpath
# tomcat-juli.jar can be over-ridden per instance
if [ -r "$CATALINA_BASE/bin/tomcat-juli.jar" ] ; then
  CLASSPATH=$CLASSPATH:$CATALINA_BASE/bin/tomcat-juli.jar
else
  CLASSPATH=$CLASSPATH:$CATALINA_HOME/bin/tomcat-juli.jar
fi
CLASSPATH=$CLASSPATH:自己的目录

然后重启
